Summary: The health risk associated with metal pollution is a global concern due to potential bioaccumulation, toxicity, and carcinogenicity. A study was conducted on over a thousand fish individuals along the heavily sediment-laden Yellow River to investigate metal bioaccumulation and evaluate the health risks to humans. The concentrations of most metals in fish were influenced by trophic levels and the metal content in the aquatic environment. Consumption of fish from the Yellow River does not pose a noncarcinogenic risk to adults and juveniles, but there are carcinogenic risks associated with Cr, As, Cd, and Pb, albeit within acceptable levels. To minimize these risks, adjustments in diet and reducing consumption of aquatic products from the Yellow River are recommended.

Summary: Trace metals and metalloids in aquatic ecosystems can have adverse effects on fish survival, especially during vulnerable life stages. It is still unclear if threatened fish species in the heavily sediment-laden Yellow River are at risk of toxicity from multiple trace metals. In this study, we analyzed the concentrations of trace metals in the river's water and fish tissues, and evaluated the metal toxicity levels for threatened fish. We found significant differences in trace metal concentrations among different threat categories of fish, and observed lower metal toxicity in certain species in specific reaches of the river.

Summary: The present study assessed the bioaccumulation of Cu, Zn, Pb, and Cr in fish species from Pulicat Lake in southeast India. The study found variations in the accumulation patterns of metals in sediment, water, and fish samples. Although some muscle samples exceeded the safe limit for Cu and Cr concentrations, the estimated daily intake remained within the standard reference dose, indicating the safety of consuming fish muscle tissues.

Summary: This study investigated the concentrations of heavy metals in carp-farming water and muscle in three major fish farms in Mazandaran Province, Iran. The results showed that the water concentrations of all metals were within permissible limits. The concentrations of heavy metals in the muscle of different carp species were also relatively low, indicating that consuming farmed carp products poses minimal health risks to humans.

Summary: This study investigates the metal levels in fish and water from the Kizilirmak River in Turkey. Differences in metal levels were found among different fish tissues, with the highest levels in the gills and liver. Consumption of the studied fish species is safe and provides nutritional benefits.

Summary: This study investigated the levels of nine heavy metals in the organs and tissues of six commercially important fish species from the Barguzin River and assessed the associated human health risks. The results showed a low level of heavy metal contamination in the fish organs and tissues, indicating a low risk to human health from consuming these fish species.

Summary: Concentrations of heavy metals in Tilapia spp. from Calapan City, Philippines were assessed. The study found that Cd concentrations in all parts of Tilapia exceeded the FAO/WHO limits, with the highest concentration in the fins. Other heavy metals such as Cu, Pb, Mn, Hg, and Zn also exceeded the limits in certain parts of the fish.

Summary: To assess metal pollution in the Wujiang River, concentrations of eight metals were examined in the water, sediments, and two fish species. The results showed that metal concentrations were generally below the water quality standards. The sediments in the lower reaches had higher bioavailability and mobility of certain metals, indicating increased risk of secondary release. Although metal concentrations in fish varied, the overall health risk from consuming fish was low for the general public due to prohibited commercial fishing.

Summary: Excessive use of fertilizers on agricultural lands and fish ponds can lead to serious pollution problems with heavy metals, causing severe health issues. A study investigated the presence of heavy metals in commonly used fertilizers and their association with heavy metals in vegetables, soil, fish species, and pond water. The research found significantly higher concentrations of heavy metals in fertilizer-applied sites compared to control groups, indicating potential health risks. Careful monitoring of fertilizer use is necessary to protect humans and animals from heavy metal exposure.

Summary: This study investigated the accumulation of cobalt in several forage crops and found significant differences in cobalt concentration in different soils, sewage water sources, seasons, and forage ecotypes. Bioaccumulation of cobalt in the food chain, caused by anthropogenic activities, was observed. The results highlight the need to prevent contamination of the food chain by cobalt-rich sewage water and to explore alternative water resources for irrigation.

Summary: The Danube, the second-largest river in Europe, has been polluted in the past and is currently facing pollution from metals due to industrialization and urbanization. Fish in the river are exposed to these metals, which then enter the human food chain, raising concerns about their safety for consumption. Recent studies have shown that the metal levels in the edible parts of the fish are below acceptable limits, but negative perceptions still persist among consumers.

Summary: The study evaluated metal concentrations in different organs of Barramundi fish and found that heavy metal concentrations were higher in farmed fish than in wild fish, possibly due to environmental conditions and dietary element concentrations. Although some metal concentrations exceeded national and international threshold limits, overall, all studied heavy metals were below the maximum permissible limits.

Summary: This study focused on evaluating the pollution levels in Dhaleshwari River in Bangladesh due to heavy metal discharge from tanneries and other industries, as well as the associated health risks of consuming fish with accumulated heavy metals. The results showed that heavy metal concentrations in water and sediment exceeded WHO and USEPA standards, with seasonal variations observed. Fish organs had high metal concentrations, especially in gills, posing health risks upon consumption.
